Derivada de cos(9x)
Answer
-9*sin(9*x)
Derivative of cos(9x)
- Rule Used
- Chain Rule
- Steps
- Identify a composite function in : use the chain rule = f'(g(x))·g'(x). The inner derivative is required because a stretch or shift of the input changes how fast the output moves.
- Differentiate the outer function, then multiply by the inner derivative.
- Final answer: -in()
A derivada de cos(9*x) é -9*sin(9*x).
